I'm also using the latest version of Chrome, but on Win XP. It works fine for me on both my own site and my local development (XAMPP).

Please note that the action is not instant; after clicking the apply button the page will reload.

Could you please tell me if you can change the amount of plugins per page on the Plugins menu? Code Snippets uses basically the same method as is used there. If it doesn't work on the Plugins page either; then it's a problem with your site, not the Code Snippets plugin.
